you could achieve a similar sound to loop windowing on the edp by using shuffle

if you write a script that has

shuffle 16 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1

then you'll just hear the first 16th of the loop over and over

if you then do

shuffle 16 2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2

then you'll hear the second

etc etc

if you then do a bounce of one of those 16ths onto a new track, you can multiply it up if you want to, but as you havn't actually changed the length of the loop, you could just overdub new material as normal, or use divide etc

the trick would be stepping through these different shuffle patterns, rather than having a separate script on 16 separate buttons. i suppose it's doable if you shuffle in 8ths, then you could have a bank on your pedalboard set up to do it

i don't know if you could use some if / then statements to select which shuffle to use - if the current granule is 1, then shuffle with granule 2 - something like this...
